Abstract

Meighan wetland catchment is located in the central catchment, it is a relatively flat plain with no elevation. Due to the destruction of natural resources, the phenomenon of desertification threatens other surrounding lands. In this study, wind speed and direction data and meteorological phenomena have been studied in an hourly format and related codes were extracted to investigate dusty days. Landsat satellite imagery was received and reviewed on a monthly basis to monitor the water status of Meighan Wetland. Then, in order to measure the effect of Meighan wetland on Arak city, wind direction data were segmented. In the months of June and July, the occurrence of dusty hours reaches its peak, among which, the high share of dust occurrence with wind direction from the dry summer lagoon is significant, and in the months of October, November, and December, no dust occurrence. Not reported. The north-east wind direction, which is more frequent in summer than the west direction, can play a role in the transfer of dust and dust from the deserts along the road (bare soils of Meighan basin) and the Meighan wetland.
